(01. mil-27) 1 Claim.

This invention relates to snow guards for roofs. It is particularly directed tosloped slate roofs in the winter time. Snow has a tendency to collect on sloped slate roofs, and after melting for a short time, the entire bank of snow on the slate roof suddenly slides therefrom and often causes injury to people.

It is therefore an object of the present invention to provide highly improved means for holding the loosened melted snow against sliding off the roof in a thick load.

In accordance with the invention, a plurality of snow guards are attached to an edge of the slate roof at spaced points, so as to prevent the snow from sliding down in its entirety.

Another object of this invention is to provide a strong and durable snow guard of the character described, which shall be relatively inexpensive to manufacture, easy to install and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will be exemplifled in the construction hereinafter described, and of which the scope of application will be indicated in the following claim.

In the accompanying drawings in which is shown various possible illustrative embodiments of this invention,

Fig. 1 is an elevational cross-sectional view through a large portion of a sloping roof provided with a snow guard, embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2--2 of Fig. 1;

Fig. 3 is a top plan view of the improved snow guard;

Fig. l is a View similar to Fig. 1, but illustrating a modified construction;

Fig. 5 is a cross-sectional view taken on line 5--5 of Fig. 4; and

Fig. 6 is a top plan view of the snow guard shown in Fig. l.

Referring now in detail to the drawings, Hl designates the lower portion of a sloping roof, the same being provided with a snow guard H embodying the invention. The roof lil is shown in the drawings as provided with overlapping slate shingles 62 attached to the roof by nails it, or by any other suitable fastening means.

The snow guard ll comprises a flat elongated strip of metal l5 which may be inserted beneath the lowermost shingle 12 at right angles, to the notches I 1.

bottom edge of the roof 1!). The strip of metal l5 may be provided adjacent the upper end thereof with a plurality of inclined notches ll extending to one side edge thereof.

Welded, soldered or otherwise attached to the lower edge of the strip I5 is a member 26 made of a single piece of wire, and having a portion 2| extending longitudinally of the strip and beyond said strip and centrally thereof. Extending from the lower end of portion M is an upwardly extending portion 22. Extending from the upwardly extending portion 22 is a downwardly looped portion 23, substantially contacting the top of portion 2|, adjacent the base of portion 22. The loop portion 23 is substantially 260 degrees in extent, and extending downwardly from one end thereof, is a portion 26 contacting the side of portion 2|, inwardly of the looped portion 23.

Extending from the lower end of portion 26, is a straight portion 21 extending longitudinally of portion 2|, and alongside the same, and extending further out than portion 22.

The nail It may be engaged within one of the After the snow melts, it cannot slide off the roof in large chunks, because of the looped portion 23 and the straight portions 22, 26. Said portions act as a barrier for the snow, preventing the snow from sliding off the roof.

In Figs. 4, 5 and 6 there is shown a snow guard I la, embodying the invention, and illustrating a modified construction, and likewise attached to a roof it having shingles l2 attached thereto by nails l3. The snow guard Ila comprises a thin, flat straight strip 30, having one or more inclined notches 3| adjacent the upper end thereof and extending to one side thereof. The lower end of the strip 30 is bent back, as at 33, and fixed to the body of the strip by a rivet 34.

Mounted on the lower end of the strip is a barrier member 35 made of a single piece of wire. Said barrier member comprises a U-shaped portion 36, extending around the rivet 34 and disposed between the strip 30 and the bent back portion 33 thereof. Extending from the arms of the U-shaped portion 36 are outwardly extending portions 36a. Extending upwardly from the outer ends of portions 36a are portions 31, and extending from the upper ends of portions 3! are crossing inclined portions 38, from which there extends parallel portions 39 projecting at the same angle as the strip 30.

It will now be understood that the portions 31, 38 of barrier member 35 serve to prevent the snow from sliding off the roof.

Obviously the guard members H and Ila may be used with any type of sloping roof having any type of shingles. A plurality of said guard members are attached to the sloping roof in spaced parallel relation.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative andnot in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A snow guard comprising a flat elongated strip of uniform width having an inclined notch at one side and adjacent one end thereof, the opposite end of said strip having a short reversely bent portion forming a loop, a rivet securing said looped end to said strip, a unitary wire barrier member having a U-shaped loop in the plane of the strip encircling said rivet, the arms of said loop member each having outwardly and upwardly extending continuing portions and a downwardly extending continuing portion crossing each other and a forwardly extending end, said ends being spaced from each other and being in a plane parallel with that of said strip.
